Mobile Yahoo and Legacy Webmail Mass-Delete Tool for Inbox Cleanups That Don't Require a Desktop

android app real project •• multiple requests

Users with 100K+ Yahoo, AOL, and Outlook.com inboxes are stuck because the official Android apps either limit selection to one screen at a time or hide bulk delete entirely. They want an Android-native client that does range-select, sender-batch delete, and date-window purge entirely on the phone with IMAP, without needing to dig out a laptop. The legacy-mail audience skews 50+ and is exactly the demographic least likely to switch to a desktop just to clean an inbox.

builder note

Don't compete with Clean Email's automation. Compete with Microsoft's broken Outlook-mobile flow. The killer feature is 'show me every sender that emailed me 50+ times in the last year, batch delete with one tap'.

Inbox-zero tooling has gone B2B SaaS (SaneBox, Clean Email) at $7-15/mo. There's a gap for a $5 one-time Android-only IMAP cleanup tool aimed at older users who want to declutter without a subscription or a laptop.

Clean Email Web-first product; mobile companion is thin and routes the cleanup back through their cloud, which the Yahoo demographic distrusts.

Yahoo Mail official app No true 'select all matching sender' or 'delete everything before date X' flow on Android.

K-9 Mail / Thunderbird for Android Generic IMAP client, lacks the bulk-cleanup workflows like 'group all newsletters from this sender and delete'.
